Spades and Ring Spacers Description

Ring spacers
Ring spacers are bored to the matching pipe ID and are the same thickness as the “single blind” that it replaces. When removing a “single blind”, either the flanges and associated piping must be pulled together to seal the line, or a “ring spacer” must be installed to fill the gap. Thick single blinds or rigid piping systems normally require ring spacers.

Spectacle Blind
A spec blind is a combination of a ring spacer and single blind. They are usually permanently installed in a piping system and rotated as needed.
